双轨无机布防火卷帘门
Double track fire curtain with inorganic cloth
特级防火卷帘为双轨、双帘面无机耐火布、硅酸铝纤维毯、防辐射布和装饰布，中间加钢丝绳，经耐高温线缝制，两面用镀锌调夹制而成，无机防火卷帘具有钢质防火卷帘的主要特性，耐火时间大于4小时，防热辐射能力强、可自带烟感、温感探测器独立工作或与火灾自动报警系统联动。配温控熔断装置，实现火灾初期的自动下降、报警，阻止火灾蔓延等。另外与钢质防火卷帘相比其优势具有背火面升温不超过CB/TPP78规定的140℃的特征，免装喷淋，具有卷帘自重轻，减轻了建筑的负荷，其安全性更可靠。
The super-grade fire-proof roll-up curtain is made of double-track and double-curtain. The curtain is made of Ayong inorganic fire-proof cloth, aluminium silicate fiber blanket, radiation-proof cloth and decorative cloth with steel wire rope in the middle. The two sides are made of zinc-plated adjusting and clamping. The inorganic fire-proof roll-up curtain has the main characteristics of steel fire-proof roll-up curtain. The fire-proof time It has strong fire ability, smokeable smoke, temperature sensor or working independently with fire automatic alarm system. The temperature control fuse device can realize automatic descent, alarm and prevent fire spread at the early stage of fire. In addition, compared with steel fireproof roll curtain, it has the advantage that the temperature of backfire surface does not exceed 140 C stipulated by CB / TPP78. It is free of spraying. It has light weight of roll curtain, lightens the load of building, and its safety is more reliable.
